What are the characteristics of sperm whales?Sperm whales are mostly dark grey, though some whales have white patches on the belly. They are the only living cetacean that has a single blowhole asymmetrically situated on the left side of the crown of the head.
The heads of sperm whales are extremely large, accounting for about one-third of their total body length. The one common theory is that the fluid that represents the hardens to wax at the time of cold it helps the whale alter its buoyancy due to this it can dive deep and rise again. This is due to the fact known as hydrostatic pressure.

Which characteristic of an extinct organism makes it best suited to be used as an index fossil?
a. an organism whose fossils show evolutionary change over time .
b. an organism that was common only in specific types of environments
c. an organism that was commonly fossilized during a specific period of time
d. an organism whose fossils are found in rocks ranging in age from ancient to recent times
Characteristic of an extinct organism makes it best suited to be used as an index fossil is an organism that was commonly fossilized during a specific period of time.
An index fossil is a fossil that is used to help determine the age of rock layers and the relative ages of fossils found in different layers. Index fossils are typically chosen because they have a wide geographical distribution, they lived during a specific time period, and they are easily recognizable. Since the fossilization process is rare and the preservation of fossils is not guaranteed, the best index fossils are those that were commonly fossilized during a specific period of time, as it is more likely that these fossils will be found in rocks of that age, and thus can be used to help date the rock layers.

Part E: Estimate Greenhouse Gas Emission
You’ll design your eco-friendly home to reduce the use of carbon dioxide compared to the average home in the state. Estimate greenhouse gas emissions for your house. Use these three government tools to generate the data you need.
First, go to the US Energy Information Administration and click “Average monthly residential electricity consumption, prices, and bills by state.” Find your state and the average kilowatt-hours of electricity used per month in your state. Multiply that number by 12 to get the amount of energy used in one year.
Then visit the EPA's Greenhouse Gas Equivalencies Calculator and enter the kilowatt-hours of energy for one year into the “If You Have Energy Data” box. Select kilowatt-hours of electricity and click Calculate. The kilowatts converted into emissions equivalents (such as miles driven and average household energy). This information will give you a better perspective on the greenhouse gas emissions for the average home in your state.
Finally, click the EPA's Power Profiler and enter the ZIP code. Choose one of the electrical companies listed (any one will work) and press Enter. Scroll down to see how much of the energy in this ZIP code comes from renewable energy and nuclear energy (a nonrenewable, cleaner energy source) compared to fossil fuel sources (oil, coal, and gas). You’ll also see bar graphs that compare your ZIP code’s energy profile to the national average.
Based on the data you gathered, answer the following questions:
What conclusion can you draw about the emissions of greenhouse gases for the average home in your state or ZIP code? What factors do you think contribute to this emission rate?
How do the emissions in your ZIP code compare to greenhouse gas emissions across the nation? Even if it’s better than the national average, is there room for improvement?
The greenhouse gas is harmful for the earth's environment, and this happens when there is a maximum amount of carbon dioxide released to the atmosphere, which is caused by a lot of human usage of fossil fuels for electricity, etc.
What are the negative effects of green house gases?Several gases are released into the atmosphere, and as a result, the atmosphere warms, negatively impacting many living things such as animals and plants. To reduce the negative consequences of this warming, the emission of carbon dioxide should be decreased.
Hence, the greenhouse gas is harmful for the earth's environment, and this happens when there is a maximum amount of carbon dioxide released to the atmosphere, which is caused by a lot of human usage of fossil fuels for electricity, etc.

Exactly 14. 5 moles of co2 are produced from burning how many moles of ch4 in excess oxygen?.
From the combustion results 14.5 mol of CH₄ in excess oxygen.
The combustion reaction is an example of an exothermic reaction because the heat generated from the combustion process is transferred from the system to the surroundings. In the combustion reaction that occurs in fire is the release of energy to the surroundings (producing heat) which causes the surrounding air (environment) to become hotter.
The balanced reaction shows that for every molecule of CH₄ consumed, one molecule of CO₂ is formed. Exactly 14.5 moles of CH₄ are needed for 14.5 moles of CO₂. Note that for every molecule of CO₂ produced, only 2 molecules of O₂ are needed.
CH₄ + 2O₂ → CO₂ + 2H₂O
You need 14.5 x 2 = 29 moles of O₂.
So, in this question, we get an excess of O2.

C. precipitation, evaporation, condensation,

D. precipitation, evaporation, runoff,
condensation, precipitation
!
Answer:
B. precipitation, runoff, evaporation, condensation, precipitation.
Explanation:
A is incorrect because in order for the water to get to the point of condensation, it needs to be evaporated into the clouds. B is correct because the first thing that needs to happen is for precipitation to occur. Then, the precipitation can become runoff and wait in a puddle, lake, ocean, etc. The precipitation is then evaporated into the clouds, where it condenses and the process starts all over. C is incorrect because in order for the precipitation to be evaporated again, it needs to run down the sides of things and gather somewhere to wait. Then, it can be evaporated. D is incorrect because it is impossible for precipitation to be evaporated before it can be one runoff. Therefore, the order is wrong.

what energy carrier compound is found in all living systems
The energy carrier found in all living systems is Adenosine Triphosphate (ATP).
What is Adenosine triphosphate?ATP is the direct source of energy for all metabolic activities in the cell. The energy bound in ATP comes from the energy released in the breakdown of organic compounds in cells, namely in the process of respiration.
ATP is formed from the process of glycolysis that takes place in the mitochondria. Mitochondria are cell organelles that have an internal membrane where glycolysis takes place. Glycolysis is the breakdown reaction of glucose from food into pyruvic acid and ATP. As an energy carrier, ATP is also found in many mitochondria.

What 7 traits did Mendel study in peas?
Seven traits that Gregor Mendel studied in peas include:
pea shape (wrinkled or round),pea color (yellow or green),flower color (white or purple),pod shape (inflated or constricted),pod color (yellow or green),position of flowers (terminal or axial), andplant size (dwarf or tall).Gregor Mendel (20 July 1822–6 January 1884) was an Austrian biologist that was widely known for his pea plant experiments. Mendel is often called the father of genetics.
He studied the inheritance of seven different traits in peas, which included height, flower and seed colors, and seed shape. To do so, Mendel first established pea lines with two different forms of a trait, such as yellow vs. green color. For generations, Mendel grew these lines until they were pure-breeding (which meant they always produced offspring identical to the parent), and then he bred them to each other and observed how the traits were inherited.

Where will nearly all of the further human population growth take place in the world? what is a foreseeable problem with this?

Nearly all of this future growth will occur in the 'South'—i.e. Africa, Asia (excluding Japan, Australia and New Zealand), and Latin America—where population size is projected to increase from 5.3 to 7.9 billion between 2005 and 2050
More than half of global population growth between now and 2050 is expected to occur in Africa. Africa has the highest rate of population growth among major areas. The population of sub-Saharan Africa is projected to double by 2050.

Global population growth and the destructive consumption habits of high-wealth countries put pressure on biodiversity and human communities, exacerbating food and water shortages, reducing resilience in the face of climate change, and making it harder for vulnerable groups to rise out of intergenerational poverty.
